Definitions

  • the invention relates to a staircase for multi-storey prefabricated houses, the staircase consisting of prefabricated room cells, the individual cells to be stacked one above the other having factory-assembled and installed stairs, with platforms being built into the room cells, between which the stairs are arranged and where There are recesses in the base plate and / or ceiling plate.
  • Such a staircase for a multi-storey prefabricated house is known from US-A-4 930 273. Recesses are provided on the floor and ceiling panels on the stacked room cells to form the staircase. In the area of the floor and ceiling panels, these platforms are connected, between which the prefabricated stairs are arranged.
  • a staircase is known from FR-A-1 465 704, which has prefabricated stairs with stair rails preassembled on stair stringers.
  • the staircase has intermediate platforms that are designed as a steel lattice construction.
  • the invention has for its object to propose a staircase of the type mentioned, in which the intermediate platform is supported in a simple manner.
  • the room cells have a floor slab with a frame made of steel profiles, rising column elements at the corners, an upper ceiling frame and fully assembled outer walls with parapet, windows, insulation and fire protection that the platforms as between the floor slab and the ceiling plate of a room cell arranged intermediate platforms are formed so that the intermediate platforms are held on one side from cross members defined between the ascending column elements of the room cells and on the other side are supported on cross members which are supported on ascending additional columns that the stairs have prefabricated steps that are used in stair strings leading to and from the intermediate platforms and that handrails are fixed to the stair strings.
  • the upper ends of the stair strings rising from the intermediate platform are expediently fixed on cross members of the ceiling frame of the respective room cell, so that each room cell has its own staircase area from the floor level to the upper level of the ceiling tile.
  • the intermediate platform is formed in two parts at different heights with an intermediate partial staircase.
  • the fire protection cladding of the stairs can be attached on the underside of the stair stringers and covering the stairs.
  • Fig. 1 shows a longitudinal section through the staircase area of a lower room cell A for a multi-storey prefabricated house.
  • This room cell has a base plate 1 with transverse steel beams 2 and longitudinal steel beams not visible in the section shown, as well as ascending column elements 9 at the corners and an overhead ceiling plate 3 with transverse and longitudinal steel beams 4 and 5.
  • the supports 6 and 7 of the base plate 8 are shown in dashed lines.
  • a fire protection cladding 23 below the stair stringers 15 or steps 16 and further fire protection plates 24 below the intermediate platform 10 can be seen from the figure shown.
  • the upper intermediate platform 11 and the stair stringers 19 with the steps 20 on the underside are clad with fire protection plates.
  • Fig. 2 shows a section through a multi-storey staircase, the dividing lines between the lower room cell A and the room cell B of the first floor according to the section line I - I and that between the room cell B and the room cell C of the second floor along the section line II - II.
  • Fig. 1 The same reference numbers as in Fig. 1 have been used for the lower space cell, i.e. the stair stringers 15 with the steps 16 lead from the lower base plate 1 to the first intermediate platform 10, from here the stair steps 18 with the stringers 17 to the second intermediate platform 11 and from here the cheeks 19 with the steps 20 to the base plate 8 of the attached room cell B of the first Floor.
  • This attached room cell B has in the same way a lower intermediate platform 30 and an upper intermediate platform 31, here again stairs 32 with steps 33 lead from the base plate 8 of the first floor to the intermediate platform 30 and then from the intermediate platform 31 corresponding stairs 34 with steps 35 to Floor plate 36 of the second floor.
  • the sectional view shows the railings 40, 41, 42 and 43 already installed and factory-fitted on the corresponding stair strings 15 and 19 or 32 and 34, as well as the extensions 37 of the additional columns 14 extending between the intermediate platforms 10 and 30 to intercept the intermediate platforms.
  • This pre-assembly of practically finished staircase sections already in the factory during the manufacture of the individual room cells means that a walk-in and practically finished staircase is immediately available at the construction site, which meets all structural requirements and at the same time corresponds to the required fire resistance class F90 for the completed building.
  • Another major advantage is that the entire staircase can be moved during a renovation without having to be separately removed and later reinstalled.
